stuff in webkit/ can't know about extensions :-/

same applies to your changes to webkit/dom_storage

Maybe call it UNPROTECTED_OTHER and PROTECTED_OTHER and have a callback on
SpecialStoragePolicy that given a URL returns the origin type?

extensionSpecialStoragePolicy can then do the chrome-extension:// magic
